JRocco...What about this 1950 Proof Franklin.??

Look at the end of the "5" and upper areas of "S & T".

Hey pinealbany,
This looks like strike/machine/shelf type doubling.
Imagine it like this:
Take a sheet of dough and use a cookie cutter to cut out a cookie----just supposed it is a cookie shaped like an "S".
Now if you take that cookie cutter and press out a fresh cookie imagine if as you were lifting the cutter away from the dough it slipped a little in your hand and pressed down again on the newly cut "S" cookie, but landed back on the cookie just a little to the side. The resulting cookie would have a little shelf like squished part on one side of the cookie where the cutter came down a little off center. This is what happens to the die, it chatters or bounces a little or may just brush against the side of the design instead of lifting cleanly off. This shelf doubled coin is made from a NORMAL die that just impacts the coin incorrectly.
Opposed to this is a true hub doubled die that has 2 clean distinct design imprints, and EVERY coin made from those working dies will show the same doubling, like the 55 DDO for example.
Here as an example is a 41 DDO, and a 55 DDO. Notice the 2 distinct letters. This working die had the doubling on the die itself and every coin it struck had this same exact doubling.
I hope I made some sense.....
